Where did all this WAP talk come from?

Currently, the number of mobile phone users in the world is exploding. Globally, mobile phone users outnumber desktop PCs. Worldwide, there are about 380 million mobile phone users, compared to 200 million PC. By 2003, mobile phone users are expected to reach at least one billion, or one out of every six people on the planet. Mobile phone users have a huge user base, and mobile telephony already has a gigantic platform for communication -- and this platform is growing every day. Now, imagine the emergence of a new technology -- one that enables all these mobile phone users to access the Internet. A mobile internet. With a thriving mobile internet, m-commerce would not be far behind. The mobile internet exists today. It is made possible by a new technology that links wireless devices to the Internet. This technology is WAP.

What exactly is this WAP thing anyway?

WAP stands for the Wireless Application Protocol. Essentially, WAP is the technology that makes it possible to link wireless devices (such as mobile phones) to the Internet by translating internet information so it can be displayed on the display screen of a mobile telephone or other portable device. How exactly do mobile phones access the Internet? Think about how the Internet currently works. In layman's terms, the Internet utilizes two types of computers -- servers and clients. Servers are the computers that host the pages that we view. The clients are our PCs, or the computers that we view these pages from. WAP technology works much in the same way. The difference is that, instead of accessing the Internet from our PCs, we are using mobile phones. The mobile phones become our clients. Servers are still hosting the pages that we view. There's a trick to all this, though. In order to connect mobile networks to the Internet, a WAP Gateway must exist. In addition, the mobile phone we are using as our client must be WAP-enabled, and the website one is viewing from the Internet must be in a WAP-format.

What is a WAP Gateway?

A WAP Gateway is an intermediary between the Internet and the mobile network. It converts our "WAP' request into a "Web' request when we send information from a mobile phone to the Internet. On the flip side, a WAP Gateway also converts a "Web' to a "WAP' request when sending information from the Internet back to a mobile phone. What do you mean the mobile phone must be WAP-enabled? Mobile phones that are "WAP-enabled' means that only mobile phones that have been built with WAP technology built into them will be able to access the Internet. Many mobile phone manufactures such as Ericcson, Motorola, and Nokia are already offering WAP-enabled phones. These WAP-enabled mobile phones do not vary significantly from conventional mobiles. The most notable physical difference is a larger screen that allows for easier use of the internet. What do you mean the web site must be in a WAP format? Web pages today are often written in HTML (hypertext markup language) which is rather too complex for mobile phones with their slower operating speeds. Mobile phones will need to access web pages that are written in WML (wireless markup language). WML greatly simplifies download times and presentation. Thus, when we hear talk of websites being in a WAP-format this means that the existing websites' original language of HTML must be converted to WML.

What is WML like?

WML is a fairly bare-bones programming language -- there's not a lot of functionality to it. It's also quite new (the first version came out in 1999). WML allows developers to specify the format and presentation of text, the hierarchies of pages, and link their pages. The hierarchies of these pages are called "decks.' The individual pages are called "cards.' WML produces static pages (or cards). Static pages only display text, and allow users to jump from one page to another through links. They're not too exciting. Are you telling me that static web pages are the only types of web pages available through mobile phones? No, this is not the case at all. WML has its own version of JavaScript, called WMLScript. WML Script allows programmers to create additional functions to their WML web pages. Currently, WML files and WMLScript files must be saved independent of each other. Thus, a number of files may be associated with a single WAP-formatted web page.

What BTREE does with WAP and SMS ?

We, at BTREE INFOTECH, use this ultramodern technology to develop WAP and SMS enabled applications and e-commerce/e-business solutions like our Cybershop-WAP version, online seats and ticket booking systems, SMS/WAP banking and customer support systems etc. We use Java servlets/JSP and ASP technologies to develop dynamic WML codes to build database driven WAP/SMS applications. We use toolkits like UPsdk, Ericsson sdk, and nokia WAP development kit. We also host WAP applications in our WAP enabled servers. We also setup local SMS servers for SMS banking and SMS based customer support systems.

We have also develped an embedded system based 'SMS manager' to automate CRM solutions with an integrated PC. The embedded system receives SMS commands from customer mobile phones, and will search the database in the PC, assemble output SMS and sends back to the clients mobile phone. For each SMS input the PC will process unique output SMS messages and will send to the target mobile. The system also provides an IVR module that assemble ouput as voice and then sends to the target mobile as voice.
